Thanks for your reply; some comments below. 2012/2/19 Kaza Kore <dj_kaza@xxxxxxxxxxx>: > As to video.

[...] An added complication here, is that I want something that will work with HDCP (AFAICS, the prosumer video equipment you mention will not accept HDCP signals). Also, I'm not really in the market for lots of video equipment. I simply want something that can switch between mutiple HDMI sources (including consumer equipment such as BluRay/DVD players), and then split the chosen HDMI signal, so that video goes directly to the screen, and audio goes to my computer for further processing. Hence, I'm not really in the market for prosumer/professional video equipment. I don't actually want the video signal into my computer at all. However, there is currently no (consumer-level) standard (except HDMI) for transferring multi-channel uncompressed digital audio between devices. Ideally, I'd want a device with HDMI input and HDMI(video) output, along with outputs for transmitting 8ch LPCM (decoded from the HDMI audio signal). The audio output could be something like 1 x ADAT, or even 4 x SPDIF (or AES/EBU) - I don't really care - as long as it could be straightforwardly connected to my computer. > Or has the HDMI switch done away with the need for a lot of this?

For now, I am using a cheap HDMI switch with an audio de-multiplexer that redirects the 2ch. bitstream to an SPDIF output. This is obviously not ideal, since it cannot handle >2ch LPCM (including the Dolby TrueHD or DTS-HD Master Audio formats), but it _is_ able to do the Dolby Digital and DTS formats that are compressed into the 2ch. stream. This is "good enough" for now, since most of my video material is DVDs (although the BluRay collection is growing slowly), and most of the high-quality audio is in computer files that I can play directly from the computer and thus does not have to traverse the HDMI switch. Considering the direction technology is moving, I might have most video and audio accessible directly from the computer in the future, thus making the HDMI switch less important (only needed for things like console games, etc.) Have fun! :) ...Johan -- Johan Herland, <jherland@xxxxxxxxx> www.herland.net _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
